This page is for playback reports regarding High Definition Content. This page will serve as a resource for users in selecting hardware for their MythTV systems.

h.264 samples of various resolutions that are often difficult to play can be found at http://x264.nl/h.264.samples/. Find the file that is most taxing to play while still playing smoothly and run the script on this page with it.

Please *only* provide samples using playback with the Internal MythTV player on this page. Do not use MPlayer, VLC, Xine, or any other player. Please do no use VDPAU or any hardware acceleration when adding information to this page. It is *purely* for purposes of determining the CPU and memory necessary to perform all decode and playback in software.

How to produce information for this page

Paste the following into a file (eg, hdplayback.sh), chmod +x the file, and run it on a file known to play back perfectly on a given system (eg, ./hdplayback.sh moviefile.mkv). It will produce an output file called hdreport.txt. hdreport.txt is in wiki format. Edit this page, find the most suitable position in the table to place the data (by CPU spec), and paste the output there. Edit the "Comments" section to share any special command line needed to get the program to play smoothly.

This script requires ffmpeg to run properly. For Matroska files, mkvtoolnix is also required. Some types of files do not report accurate information. Check the output for missing fields and fill in as necessary.

Please disable clock stepping on your processor, or run something intensive in the background, to provide an accurate clock rate

User Reported Data

Please include reports for MythTV only. Reports for mplayer, vlc or any other media player are unhelpful and belong in the wikis of the respective project. Processors speeds marked in red are likely incorrect due to AMD Cool'N'Quiet or Intel Speedstep.
